The most discreet time to find this cache will be outside of business hours (M-F, 9-5), although privacy at GZ really shouldn't be an issue.
The name of this cache does not refer to the parking garage nearby, but to the open paved area that will be at your back while you search GZ. It is identified by the number 4-0-1.![smiley smiley](https://www.geocaching.com/static/js/CKEditor/4.4.0/plugins/smiley/images/regular_smile.png)
